Abstract (en)
[origin: WO9012901A1] The invention concerns a process, not using chlorate or nitrite, for the production of nickel-containing and manganese-containing zinc phosphate films on steel, zinc and/or steel and zinc alloys by spraying, spray-dipping and/or dipping, using an aqueous solution. An organic oxidizing agent is added, primarily to depolarize the nascent hydrogen produced.
